RE: [SCL-3] using of system properties in subject of SMTPAppender
Usually a customer is served within one separate thread, isn't it? If yes, you
can use the MDC (mapped diagnostic context). You put a value into it:
MDC.put(CUSTOMER, SOME NAME) at the begin of the session (probably in a
servlet listener) and reference this value with the layout pattern
%X{CUSTOMER}.
Do not forget to remove the value when session terminates!

Subject: [SCL-3] using of system properties in subject of SMTPAppender
Hi,
I have a 1 server app and many clients app on different servers.
Obviously I wanted to know from which server the email comes,
so I used
this:
log4j.xml
appender name=email class=org.apache.log4j.net.SMTPAppender
param name=BufferSize value=512 /
param name=SMTPHost value=my_smtp_host /
param name=From value=AutoBot /
param name=To value=my_em...@someserver.com /
param name=Subject value=Agent on [${HOSTNAME}] has
encountered error /
layout class=org.apache.log4j.PatternLayout
param name=ConversionPattern
value=%d{HH:mm:ss} [%t] %p %C
(%L) %x - %m%n /
/layout
filter class=org.apache.log4j.varia.LevelRangeFilter
param name=LevelMin value=error /
param name=LevelMax value=fatal /
/filter
/appender
and since system property has to be setup before configuring
log4j, I use this in my code.
Main class
//create system property to hold server name
System.setProperty(HOSTNAME, InetAddress.getLocalHost
().getCanonicalHostName());
//reconfigure log4j so it picks up HOSTNAME property
DOMConfigurator.configure(getClass().getClassLoader().getResource(
log4j.xml));
Then Im receiving emails with subject like this: Agent on
[127.0.0.1] has encountered error.
So far so good.
And now I have request to include customer name in subject.
I have no problem to include it in stack trace, but since I
cannot set customer name the same way as I did with IP (there
are multiple customers handled by my app so I cannot just use
System.setProperty(CUSTOMER, SOME NAME)).
I though of solution to set this property when exception is
catched and reconfigure log4j after setting proper customer
name into system property.
But I think it is politelly said ugly.
Can some1 suggest a better way maybe?
Thanks, Zbynek

Re: Set Root Log Level on command line
You can specify a system property on the command line and expand it in the
configuration.
java -DrootLevel=INFO ...
and in your configuration file do:
log4j.rootLogger=${rootLevel}

Hi All
Is there a way to set the root log level on the command line?
We have an application that runs either in Simulation mode or in Live mode.
Depending on the mode, the log level needs to be debug or error. It would be
very inconvenient to have two different log4j config files, because all
other settings will be constant.
thanks for your help

Re: log4j
There is an intro on the website, http://logging.apache.org/log4j/1.2/manual.html. Maybe that will not answer your question, but it will provide some background that may help you formulate your question. As it is written, it is unclear whether your situation is: a) There is an existing appender that I want to use and I do not know how to configure it and attach it to the hierarchy so it can process events. b) I need to implement a custom appender that process events by doing something not supported by the available appenders and I do not know how to implement it. For situation a, read the short guide previously mentioned. For situation b, identify the appender that is closest to your desired functionality and what you need it to do differently.

Re: using of system properties in subject of SMTPAppender
If it can be in the body of the email, then there are many ways that you could
customize the rendering of the message. Since it appears to be a very low
frequency occurrence, you could do something like:
if(logger.isErrorEnabled())
{
string msg = Client + clienName + encountered unexpected exception;.
logger.error(msg, e);
}
If you really want it in the subject, you will likely need to extend
SMTPAppender. You could create an object that represents the combination of
the server context and the message (or just the context if you don't need the
message parameter)
logger.error(context, e);
or
if(logger.isErrorEnabled())
{
logger.error(new MyCustomObject(context, msg), e);
}
The toString method of the first parameter will be used for the message. Your
customized SMTPAppender can recognize the message parameter object and extract
whatever information you need for the subject line.

Re: is it possible to have different log level for same package
Set the logger's level to the lower level and one of the appenders to a higher level. The event will get pass the check on the logger and will pass the check on one of the appenders and not the other. log4j.logger.com.foo.hello=DEBUG,FOO_1,FOO_2 log4j.appender.FOO_1.threshold=ERROR On May 17, 2011, at 10:33 AM, Nitin Kumar Gupta wrote: suppose I have a package com.foo.hello , can I define log level and appender such that error logs goes to one file and all other (even including error, if possible) goes to another file.
